Whoever drew this cartoon, does not really care for accuracy, much like Trump.
President Obama shook hands with the leaders of Turkey, and Cuba and Putin, when he met with them. He did congratulate Putin in 2012. At the time, things were a bit different.
This time around, the UK, France, (Germany??), and the US, had just expelled a bunch of Russian diplomats, and they expelled a bunch of ours, in a tiff over the Russian poisoning, again, of Russians in London.
As far as I remember, it was mostly the Republican lawmakers, who issued negative statements, and were caught off guard by what Trump did, given all the poisoning and deportations tension.
Trump never met with Iran's President. He did shake hands with Iran's foreign minister.
As far as I know, I don't recall President Obama congratulating them on anything.
